Description (partial)

<Prompt> element fails to play the recorded prompt in the <record> element (stored in a variable) on VVB, if the
grammar (<grammar> element)  isn't' specified for the <prompt>

For instance, 

 // The part of vxml doc that does the recording. The record element to record the prompt stored in variable RecordTest //

<vxml xmlns="xxxxxxxxxxxxxxl"; version="2.1" application="/CVP/Server?audium_root=true&calling_into=diva_admin&session_id=" xml:lang="en-US">
<meta name="maintainer" content="IBM" />
<form id="audium_start_form">
<assign name="audium_vxmlLog" expr="''" />
<assign name="audium_element_start_time_millisecs" expr="new Date().getTime()" />
<goto next="#start" />
<form id="start">
<assign name="audium_vxmlLog" expr="audium_vxmlLog + '|||audio_group$$$' + 'PromptBeforeRecording' + '^^^' + application.getElapsedTime(audium_element_start_time_millisecs)" />
<goto nextitem="RecordTest" />
<record name="RecordTest" modal="true" beep="true" maxtime="60s" finalsilence="1s" dtmfterm="true" type="audio/wav">
<prompt bargein="false">
<audio src="http://mediaserver:80/IVR/cvpcs013/diva_admin\test_admin_recordtest_en.wav">Begin recording at the tone, when finished press the pound key</audio>

// This is the other part of vxml doc. Here is the prompt element being used to play the recorded prompt by passing value expr ="RecordTest //

<field name="PlaybackRecordedTest" modal="false">
<property name="inputmodes" value="dtmf" />
<property name="timeout" value="0.25s" />
<prompt bargein="true" />
<prompt bargein="true">
<value expr="RecordTest" mode="recorded" />
<prompt bargein="true" />
<catch event="noinput">
<submit next="/CVP/Server" method="post" namelist="RecordTest audium_vxmlLog" enctype="multipart/form-data" />
<submit next="/CVP/Server" method="post" namelist="RecordTest audium_vxmlLog" enctype="multipart/form-data" />

Above doc would work on IOS and recorded prompt is successfully played back however the same document fails with the semantic 
error on VVB
